This high-speed digital signal processing unit is engineered specifically to monitor pressure pulsations in gas turbines and centrifugal compressors. By analyzing dynamic pressure fluctuations, it identifies combustion instabilities and aerodynamic surge conditions that can lead to catastrophic hardware failure or shortened component life.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"w-fit min-w-(--thread-content-width)\"\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eChannel Capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4 independent dynamic pressure input channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMeasurement Types\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDynamic Pressure (pulsation), Static Pressure (bias), and Peak-to-Peak values\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSignal Resolution\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e24-bit A\/D conversion for ultra-high fidelity waveform analysis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTransducer Compatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSupports high-sensitivity piezoelectric pressure transducers and Proximitor sensors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFrequency Response\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eConfigurable high-pass and low-pass filtering (typically 5 Hz to 20 kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlarm Logic\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIntegrated Alert and Danger setpoints with user-defined time delays\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSystem Interface\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSeamlessly communicates with the 3500\/22M Transient Data Interface\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePhysical Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2.2 cm x 12.4 cm x 12.6 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.8 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOperational Application\u003c\/h3\u003e\n\u003cp\u003eThe 140734-05 is critical for Lean Pre-Mixed (LPM) combustion systems where flame stability is a constant concern. It detects \"combustion humming\" or acoustic resonances within the turbine liner. When pressure levels exceed safe limits, the module initiates a high-speed protective trip via the rack’s relay modules, shielding the turbine from vibration-induced cracks and thermal stress.\u003c\/p\u003e\n\u003ch3\u003eEngineering FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ\u003c\/strong\u003e: Does the 3500\/64M provide raw buffered outputs for external analysis?\u003cbr\u003e\u003cstrong\u003eA\u003c\/strong\u003e: Yes, the module includes buffered transducer outputs accessible via the front panel BNC connectors, allowing engineers to connect external oscilloscopes or dynamic signal analyzers without interrupting the protective monitoring functions.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":48746755752188,"sku":"3500\/64M 140734-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/350070M_176449-09.jpg?v=1772264811","url":"https:\/\/www.electronicplc.com\/products\/bently-nevada-3500-64m-140734-05-dynamic-pressure-monitor","provider":"Electronic PLC","version":"1.0","type":"link"}
